Question about mac 130 and 188?

I like the 188 better the other one is quite short and I like having a brush that is longer so that it's more flexible. It's a great brush and has no shedding, maybe one hair will pop out when you clean them at that's it ! So that's great. Sigma brushes are also amazing, I only have 2 or 3 Mac brushes, and the rest are all mostly Sigma because the quality is just as great if not better than Mac sometimes and they are WAY cheaper. They also only shed like one hair when washing them! Very high quality for a way cheaper price and they are almost exactly the same.
